I have a Samsung phone, tracphone, with andriod 4.3.
talk back and explore by touch are both active.
When trying to use the phone, very short pauses are interpreted as a long pause, bringing up the speed dial dialog box. This makes it very difficult for a new smart phone user to make a phone call.
I did find the option to change the pause length on the device, but this is NOT a solution to the issue.
I have searched and am not able to find a way to disable or completely remove speed dial. It will never be used, so I am ok with completely removing it from the phone. Searching Google only returns results on how to delete or modify a speed dial number.
